摘要
研究了六甲基二硅胺烷(HMDS)作为锂离子电池电解液的稳定剂对电解液稳定性和电化学性能的影响。将两种不同的电解液经过60℃/24 h高温储存,取样分析检测电解液的H2O和HF的含量变化,并用两种不同的电解液制作电池进行85℃/4 h高温储存和电化学性能测试。结果表明,HMDS的加入明显提高了锂离子电池电解液的储存稳定性及热稳定性,同时可以改善锂离子电池的电化学性能和循环性能。
Using hexamethyldisilazane（HMDS） as stabilizer of Li-ion battery electrolytes,the influences of HMDS on the stability of electrolyte and electrochemical properties of Li-ion batteries were studied.The changes of H2O and HF content of the two different electrolyte stored for 24 h at 60℃,were analyzed.And the electrochemical properties of the batteries,which were made of two different electrolytes and were stored for 4 h at 85℃,were determined.The results indicated that adding HMDS obviously improved the storage stability and thermal stability of electrolyte of Li-ion,and improved the electrochemical properties and cycle performance of Li-ion batteries.
